“…The investigation of other effective and less expensive adsorbents demonstrated peat soil capability, clay minerals, chitin-chitosan and hydroxyapatite. 17,18 Clays are important class of materials that are readily available in nature. These are used as very good adsorbents, decolouration agents, ion exchangers, molecular sieves, catalysts.…”

Montmorillonite-Fe3+ (MMT-Fe3+) nanoclay mineral was successfully prepared using a ferric chloride precursor. The prepared sample was characterized using IR, XRD, BET and SEM-EDX. We have explored the highly efficient and environmentally benign MMT-Fe3+ for adsorption of Crystal Violet (CV) dye from aqueous solution under ambient conditions. The MMT-Fe3+ was interacted with CV dye solution at different pH, temperature and solid-to-liquid ratio. The concentration of CV dye removal was estimated from its optical density at λmax = 590 nm using UV–Vis spectrophotometer. The CV dye removal was rapid at basic pH and increases with temperature up to 40 °C. A complete reduction (100%) was occurred in about 7 min at pH 7 and 10 while at pH 3 in about 10 min. The time taken for complete reduction at 0, 30 and 40 °C are 10, 7 and 5 min respectively. The removal followed by adsorption of dye molecules on the spent nanoclay mineral was evident from SEM/EDX analysis. More importantly, MMT-Fe3+ could be separated and retrieved easily after the reaction by centrifugation from the degraded CV dye solution. The experimental results of CV dye removal from MMT-Fe3+ follows the pseudo first order kinetics. This study reveals that MMT-Fe3+ has the potential to be used as reductant/adsorbant to remove cationic pollutants effectively and rapidly from drinking water and large scale of industrial wastewater.

“…Hydroxyapatite can be extracted from bovine and pigs bones, fish scales [7][8][9][10][11][12] and can also be synthesized from natural calcium sources such as hen's eggshells, shells, corals [13][14][15] through chemical reactions. Hen's eggs are among the most consumed foods in the world and, therefore, a large amount of waste is generated.…”

“…Ca-P can be of natural [14][15][16][17][18][19] or synthetic origin [4,6,7,11,20,21]. It can be prepared using several methods such as: aqueous precipitation [7,17,22], sol-gel method [10,[22][23][24], solid reaction [25], and hydrothermal [26,27]. The synthetic Ca-P is an alternative to the natural material because of its chemical, biological and mechanical properties [4,15,28].…”

The antibacterial activity of non-stoichiometric calcium phosphate particles prepared by precipitation under controlled experimental conditions at pH∼9 and sintered at high temperature was studied against Staphylococcus aureus bacteria. The effects of operating parameters developed according to an experimental design of Plackett-Burman type on the physicochemical characteristics and the capacity to inhibit bacterial growth were identified using a thermal analysis (TGA-DTA-DSC), x-ray Diffraction (XR), Raman Spectroscopy, Scanning Electron Microscope (SEM) and the Kirby Bauer Method. The XRD spectrum shows that the synthetic crystalline nanoparticles powders consist of multiphasic calcium phosphate β-TCP/β-CPP/OCP/HA and that the average particle size is between 56 and 123 nm calculated by the Debay-Shearer equation. The Raman spectrum of sintered powder shows the main absorption bands that are assigned to the asymmetric / symmetric P-O stretching vibrations in PO 4 −3 and the symmetric O-H stretching mode of the hydroxyl group in addition of Ca-PO 4 and Ca-OH modes. The samples were found to possess different morphologies consisting of nano-rods of different lengths, semi / spherical structures and fine granules, in addition to irregular clusters. The antibacterial tests results showed that the high concentration calcium phosphate powder exhibited better antibacterial activity against Staphylococcus aureus bacteria with inhibition zones ranging from 0.2-0.7 cm.
